Bendtner, 22, has played just 74 minutes in the Premier League this season, and has revealed his frustration with life on the fringes of Arsene Wenger's team.

Injuries kept him sidelined until October, but the form of team-mates has restricted him to substitute appearances in the top-flight, and he has made only four starts since this season.

And Olsen warned the Arsenal striker, who played and scored for his country at the World Cup in South Africa, that he faces being axed from the Denmark side if he fails to prove his worth at club level.

"Thinking with the eyes of the Danish national team, you have to have minutes and you have to have enough games, and if he's not playing in Arsenal we cannot use him of course," Olsen told Sky Sports News.

"So it's important not only for Nicklas Bendtner but for all the players that they are playing. Bendtner has not been 100% fit for a year. We saw also in the World Cup he was not 100%.

"And he has not played in the autumn, he has not played many minutes for Arsenal. We hope he will come back and show the talent he is.''

England have confirmed a friendly against Denmark in Copenhagen for February 9, when Bendtner will hope to be involved.

Olsen declined to suggest Bendtner should consider a move away from the Emirates Stadium, explaining: "It's very difficult for me to say. It's a question of playing enough games.''
